Signal Generator
A generator of a signal of a given shape.
blockType: SignalGenerator
|
Path in the library: |
Description
The Signal Generator unit can generate one of four different waveforms:
-
Sine
-
Rectangular
-
Sawtooth
-
Random
Waveform parameters can be set in hertz or radians per second. Using the parameters by default, you will get one of the following waveforms:
| Waveform parameters | Output signal |
|---|---|
Sine |
|
Rectangular |
|
Saw-shaped |
|
Random |
|
A negative value of the Amplitude parameters causes a 180 degree phase shift.
The settings of the Signal Generator block can be changed during simulation to quickly determine how the system reacts to different types of signals.
The Amplitude and Frequency parameters define the amplitude and frequency of the output signal. The parameters must have the same dimensions (after scalar expansion).
